Melbourne VIC, Australia, 25 August 2015 |

A strong showing at last week’s Cincinnati Masters has boosted Australian young gun Thanasi Kokkinakis back inside the top 70.

Kokkinakis, who qualified for the tournament and then beat world No.31 Fabio Fognini in the first round, vaulted nine places to 70th, leap-frogging world No.72 John Millman for the fourth Australian ranking.

The South Australian Kokkinakis peaked at No.69 in June.

Meanwhile, Jordan Thompson cracked the world’s top 200 after winning his second straight Futures title in Bangkok.

The Sydneysider, who currently owns a 10-match winning streak, rose 21 places to a career-best ranking of No.193.

In the process, he also rose to 10th in the Australian rankings, overtaking Luke Saville.

Tomic has played regularly in the Egyptian resort city in 2015, winning one title and reaching a further three finals.
